Scimitar syndrome is a rare congenital cardiopulmonary malformation characterized by hypoplasia of the right lung and drainage of the right pulmonary veins into the vena cava inferior. It may also be associated with cardiac dextroversion and anomalies of the tracheobronchial system, cardiovascular system, and diaphragm. Some cases are asymptomatic with others diagnosed in early-childhood period with pulmonary hypoplasia and other associated malformations. We present here a patient whose venous return of the middle and lower lobes of the right lung is into the superior vena cava, which is a very unusual finding for this disorder.

Endovascular interventions in cancer patients with compromise of the mediastinal vasculature: a review.

The mediastinal vasculature can be affected by various etiologies in cancer patients. Both direct and indirect sequela of cancer may result in life-threatening clinical presentations. Tumor growth may cause vessel narrowing and decreased blood flow from either extrinsic mass effect, invasion into the vascular wall, or tumor thrombus within the lumen.

Cardiology, Lower Bucks Hospital, Bristol, USA.
Inferior vena cava (IVC) anomalies are rare congenital pathologies related to variations of agenesis, hypoplasia, or atresia, predisposing patients to thromboembolic events secondary to an alteration in venous drainage with resultant stasis. This is a case report of a 27-year-old male without significant medical history presenting for a fall after playing recreational basketball with associated pain and swelling in his left lower extremity. After his symptoms progressively worsened, he came to the emergency room for an evaluation where an ultrasound (US) of the extremity showed extensive deep vein thromboses (DVT).

Intracardiac migration of inferior vena cava (IVC) filter or stent is a rare but potentially fatal complication of endovascular venous device placement. There is no consensus whether migrated stents should be surgically removed by open cardiac surgery or retrieved by the percutaneous endovascular route and whether an intervention should be performed immediately or expectantly. Herein, we report a 39-year-old female who received emergent left lobe living donor liver transplantation (LDLT) owing to posthepatectomy liver failure.

Introduction: Mediastinal paragangliomas are rare neoplasms arising from extra-adrenal neural crest cells, presenting as either functional or nonfunctional tumors. Clinical manifestations range from catecholamine-related symptoms to physical compression effects. Accurate recognition of these tumors is crucial for diagnosis and management due to their rarity and association with vital mediastinal structures.

Purpose: Breast cancer radiation therapy (RT) techniques have historically delivered mean heart doses (MHDs) in the range of 5 Gy, which have been found to predispose patients to cardiopulmonary toxicities. The purpose of this study was to apply artificial intelligence (AI) cardiac substructure auto-segmentation to evaluate the corresponding substructure doses, whether there are laterality- and technique-specific differences in these doses, and if the doses are significantly associated with cardiorespiratory fitness after state-of-the-art RT planning and delivery for breast cancer.
Methods And Materials: Cardiopulmonary substructures were AI auto-segmented.
